Course Outline
SOA 2.0 is the combination of traditional Service Oriented Architecture and Event-Driven Architecture. Software modules (such as Web Services) become related to Business Components, and real-time alerts and event notifications brought in to the orchestration too.
The original SOA concept was not typically event-driven - rather it has traditionally featured direct calls from one piece of software to another in a client-server process.
Oracle and Sun are championing the implementation of SOA 2.0, through their respective Fusion Middleware and JavaEE enterprise platforms.
The substance of SOA 2.0 is considered by some parties as purely "Advanced SOA"...However you want to label it, there are several important features which should prove beneficial to any organisation striving to implement a Service Oriented Architecture to improve its workflow and business processes.
